Elvis Presley was known for many things, but among them was his preference for a calorie bomb of a sandwich called the Fool's Gold Loaf. It consisted of a hollowed out loaf of bread filled with an entire jar of peanut butter, an entire jar of jelly and a full pound of bacon.

But that ridiculous concoction is nothing compared to the Fat Shack sandwich.

As the eponymous offering of the Fat Shack restaurant franchise, the Fat Shack sandwich lives up to its name. It's a bread roll filled with cheesesteak, chicken fingers, mozzarella sticks, jalapeno poppers, french fries, onion rings and then smothered in your choice of sauce.

And if you're the kind of human being that's willing to risk invasive heart surgery for the chance to ingest a Fat Shack sandwich, you're in luck. A Fat Shack restaurant is coming to 2858 W. Berry St. in Fort Worth, just a block away from TCU.

And it's planning more locations with the backing of Mark Cuban, the Dallas Mavericks owner and billionaire investor who stars on Shark Tank.

Founder Tom Armenti started Fat Shack in Fort Collins, Colorado, in 2011, inspired by the lack of late-night food options in his college town. Amenti appeared recently on Shark Tank, where Cuban agreed to put $250,000 into the company for its expansion in exchange for a 15% stake.

"Done. Let's go get fat," Cuban said, according to CNBC's recap of the show. Cuban and the other TV show investors also liked Fat Shack's $22 million in lifetime sales.

The Fort Worth location is scheduled to open May 21. A Fat Shack opened in Denton in 2016.

In addition to the Fat Shack sandwich, its menu offers all sorts of munchies to fill cravings that only seem to hit after 10 p.m. You can order burgers, wings and a wide array of fried shareables. And then there are the desserts: You can have your choice of Oreos, Rice Krispie Treats, cookies, Twinkies and funnel cake bites -- all of them battered and deep fried.
